Deep drawing of half-cells for L-band cavities with
the new press machine at KEK. Test operation of the 150t press machine
is under way at the cavity production
pilot plat. Dozens of cells have been drawn out of Nb disk sheets
in the recent past. The focus topic of this study is to optimize the
shapes of the dies to use for producing mid-cells of TESLA-style
cavities to build at KEK and elsewhere in the near future. (2010/09/21 15:54:23)
